Leaf explants of Echinacea purpurea L. taken from aseptically germinated
seedlings were inoculated with A. tumefaciens strains EHA105, carrying a binary
vector conferring herbicide resistant bar gene and fungal resistant chitinase gene.
Glufosinate ammonium‐resistant shoots were regenerated on a medium
containing BAP and NAA at a concentration of 4.88 and 0.053 μM, respectively.
A subsequent transfer of shoots to medium containing BAP was necessary for
stem elongation and leaf development.

4-Hydroxy-2-trans-nonenal (4-HNE), one of the major end
products of lipid peroxidation, has been shown to induce
apoptosis in a variety of cell lines. It appears to modulate
signalingprocesses inmore thanonewaybecause it has been
suggested to have a role in signaling for differentiation and
proliferation. We showfor the first time that incorporation
of 4-HNE-metabolizing glutathioneS-transferase (GST)
isozyme, hGSTA4-4, into adherent cell lines HLE B-3 and
CCL-75, by either cDNA transfection or microinjection of
active enzyme, leads to their transformation. ...
Learning how to write a coherent, effective text is a difficult and protracted
achievement of cognitive development that contrasts sharply with the acquisition of
speech. By the age of 5, spoken language is normally highly developed with a working
vocabulary of several thousand words and an ability to comprehend and produce
grammatical sentences. Although the specific contribution of a genetic predisposition
for language learning is unsettled, it is apparent that speech acquisition is a natural part
of early human development.
The diversity and specialization in orchid floral morphology have fascinated botanists and collectors for centuries. In the past 10 years, the orchid industry has been growing substantially worldwide. This interesting book focuses on the recent advances in orchid biotechnology research since the last 10 years in Taiwan. To advance the orchid industry, enhancement of basic research as well as advanced biotechnology will provide a good platform to improve the flower quality and breeding of new varieties.
Colin Munro MacLeod is recognized as one of the founders of
molecular biology for his research concerning the role of
deoxyribonucleic acid (DNA) in bacteria. Along with his colleagues
Oswald Avery and Maclyn McCarty, MacLeod conducted
experiments on bacterial transformation which
indicated that DNA was the active agent in the genetic transformation
of bacterial cells. His earlier research focused on the
causes of pneumonia and the development of serums to treat
Compared to other ecosystems, wetlands have received an exceptional amount of
attention. Wetlands are valuable as sources, sink and transformers of a multitude
of chemical, biological and genetic materials. They stabilize water supplies, clean
polluted waters, protect shorelines, and recharge groundwater aquifers. They have
increasingly become recognized for their unique ecological functions in the
environment and are the focus of increased research by scientists and study
programs by schools, communities, and nature centers.
Plant tissue culture
Most methods of plant transformation applied to GM crops require that a whole plant is regenerated from isolated plant cells or tissue which have been genetically transformed. This regeneration is conducted in vitro so that the environment and growth medium can be manipulated to ensure a high frequency of regeneration. In addition to a high frequency of regeneration, the regenerable cells must be accessible to gene transfer by whatever technique is chosen (gene transfer methods are described in Chapter 3).
By playing a role in the near-annihilation of a species, Theodore Roosevelt,
the president of the United States at the turn of the twentieth century, unwittingly
laid the groundwork for the most dramatic triumph yet in the use
of artificial insemination (AI) to rescue a species from extinction.
In the early 1900s, waves of immigrants from Europe settled in the
American Midwest. As humans transformed the land, they declared war
on a perceived pest: the prairie dog.
The shifting market trends posed a significant challenge to De Beers’ preeminent position. Throughout the
1990s, the company’s inventories increased while its sales remained flat.
To address this issue De Beers chose a transformational strategy: instead of maintaining its long-standing
role as steward of the entire industry, it would become a leader in driving consumer demand.
One of the key elements of that transformation was a program called Supplier of Choice. Launched in 2003,
the program aimed to shift some of the responsibility for marketing to other players in the industry.
Plants that have features and characteristics of other species, other genera,
other families and even other kingdoms - such as bacteria and mammals -
have fascinated man since the dawn of history. Such phenomena, recorded
in several mythologies, were in the realm of miracles and the work of God.
Now they seem to become realities, though not exactly as described in the
The analysis by Tirole (2008) of maturity transformation by financial intermediaries such as
pension funds and insurance companies which have (uncertain) long-term liabilities (and
assets of a shorter maturity) carries this Keynesian tradition further. In the presence of
macroeconomic shocks that affect everybody simultaneously, he argues, private sector
assets are not useful. Instead what is needed is an external risk-free store of value such as
The third model is constructed by CIBC, following their usual data mining procedure for
a direct marketing campaign. The modeller at CIBC trained the model, and then passed
on to us the validation result. The supervised learning algorithm of their choice is linear
logistic regression. A considerable amount of time is spent on data preparation, including
variable selection, variable transformation, and variable imputation.
The first step in their modelling procedure is to significantly reduce the number of input
variables by performing exploratory analysis on the data.
The past one year and a half has been a period of unprecedented changes for
the media industry in the Arab world and elsewhere. Within a short period of
one year since the release of the second edition of the Arab Media Outlook, the
contours of the world economy underwent transformations that shocked even
the most pessimistic observers. The media could not have remained unaffected
by such a cataclysmic turn of events.
In this section, we aim to use a comparative analysis between the Arab Region
and the rest of the world to assess the current state of the media industry and
identify key opportunities for growth. We will assess the similarities between the
media industry in the Arab Region and the global landscape, such as changing
consumption trends, the evolution of new platforms and new monetisation
